T all whom t may concern.'

Be it known that l, losnrri Sinsrninn, a citizen of Germany, and a resident oi Lafayette, in the county oi Tippecanoe, State of indiana, have invented certain new and use- :tul improvements in llflindows, of which the 'following is a specification.

My invention relates to windows and covers several improvements in construction, arrangement and operation.

My invention is particularly adaptable in windo-ws of the sliding type. Ylt has been quite ditlicult, particularly for the housewiie, to wash windows ot this type from the inside of the house. One oil the main objects of my invention is therefore to provide such construction and arrangement as'will enable the upper and lower sashes of a window to be swung inwardly in convenient position for washing. By means of in v con struction and arrangement the upper and lower sashes can be raised or lowered in the ordinary manner and can also be swung downwardly to be in horizontal position on the window* sill and entirely within thel room so as to be readily accessible.

T he construction and arrangement involving swinging of the windows in addition to their vertical v movement accomplishes another very important feature, namely the ability to adjust the windows themselves for proper ventilation of the room, thereby elim inating the necessity of special window ventilators.

i-'inother important obj ect olf my invention to provide such construction and arrangement that the sashes can he readily bodily rennnf'ed from the window trame without the necessity of taking oil guide strips or other window parts. I

Another object of the invention is to provide improved and simple construction and arrangement for sealing the window against the` weather, thereby avoiding the necessity of storm windows. i

The above and other features oil: my invention are clearly illustrated on the accompanying drawings, in which Fig. 1 is a front elevational view oli a window with the lower sash swung down,

Fig. 2 is a sectional view on the plane 2 2 of Fig. 1,

Fig. 3 is a similar sectional view showing the lower sash only partly swung,

Fig.k t is an enlarged horizontal sectional view throughk one side of the' window traine i andl windowsashes, the sashes having been slnitedv vertically to bring their weight chain engaging points in the section plane,

llig. 9 is an enlarged. sectional view on plane 9 9 oi Fig. 2, and

Fig. l() is an enlarged sectional view construction shown in Fig. 9.

rllhe trame of the window shown comprises the outer sill or ledge 11, the inner sill 12, the seating board 13 for the lower sash, the top board 14, and the side wall structures desiOnated as a whole 15 and 15. As the construction andv arrangement of the window side mechanism is the same at each side oi the window l shall apply reference characters to only one side structure, it being understood that the same references apply tothe opposite side.

Referring particularly to Fig. l each side structure has inner and outer parts or wall structures 16 andi 17 respectively. lila ch outer wall structure comprises a pulley stile 1S for providing guiding means .tor thek lower sash, an outer pulley stile 19 for providing.guiding means for the upper sash, and a weather strip stile 20. The board 19 has tongue and groove connections 21 and 22 with the stile 18 and board 2O respectively-r these connections securely holding the stiles together and sealing them against the entrance ot cold or dust.

,liunning lengthwise of each stile 19 from ot the vthe top close to thebottom thereof is a groove or channel 23 into which channels trunnion pins 24; at the lower end of the upper sash are extended, these pins being loosely engaged in pockets 25 formed in the sash so that they can be readily withdrawn. At each side of the window the outer end of the Jtrunnion pin is provided with a. circumferential groove 26 to receive the end link of a weight supporting cord or chain 27. (Fig. 7 The chains extend upwardly in the channels 23, and at the upper end of such channels the chains extend around pulleys 28, the other en ds of the chains connecting with weights 29 which are in the chambers 30 formed between the outer and inner walls 1G and 17 of the frame sides. At the upper end of the upper sash and extending through the side walls thereof are the bolts 3l which are of the well known construction, springs inside of the pockets for the bolts tending to shift the bolts outwardly to hold their outer ends in the channels 23. These bolts and the trunnion pins 24 extend into the channels and hold the upper sashin its vertical path during the ordinary raising and lowering thereof. The upper sash is of Aordinary construct-ion comprising the rectangular frame 32 and the window frame 33. l

The lower sash comprises the rectangular frame 34 and the window pane 35, and at each lower corner of the sash there is a trunnion pin 36 similar to the pin 24 for the upper sash already described, these pins for the lower sash being engaged by the ends of chains 37 which extend upwardly in the channels 38 of the side boards 18 where at the upper ends of these boards they pass around pulleys 39 and at their other ends support the weights 40 in the chamber 30. Secured to the inner face of each side board 18 in front of the channel 38 therein, and countersunk so as to be flush with the inner face of the board, is an escutcheon plate 4l. These plates extend downwardly from the top of the frame to a short distance below the center line of the window, and each` plate has a Centrally extending slot 42 from which pockets or notches 43 open into the front section of the strip. These slots and notches co-operate with the pins or studs 44 extending laterally from the upper ends of the supporting brace bars 45, there being a brace bar at each side of the frame. Each brace bar has a longitudinally extending slot 46 which at its lower end receives the end of a bolt 47 extending through the upper corner of the lower sash, the constructionl and arrangement of these bolts being clearly indicated in Figs. 5 and 6. The bolt is slidable in a pocket 48 in the sash side wall and the stem 49 extends inwardly therefrom and terminates in a handle 49 at the inner side of the sash wall, a compression spring 50 tending to force the bolt 47 outwardly7 b-ut a flange 51 on the stem limiting such outward movement. Secured to the outer end of each bolt and extending radially therefrom is a latch plate 52 whose purpose will be presently described.

The bolts 47 together with the bolts 36 at the lower corners of the lower sash engage in the channels 38 and hold the'lower sash to its vertical path during ordinary raising and lowering of the sash.

Describing now the operation, the brace bars 45 will normally be parallel and coincident with the escutcheon plates 41 and the bolts and pins of the sashes will be in their i W hen the lower sash is at vertical position in the window frame, these plates are turned a distance so as to bringtheir ends behind the rear section of the escutcheon plate 4l, and the bolts are then prevented from being withdrawn. Just before withdrawing the bolts for the purpose of swinging the lower sash, the bolts are slightly turned to bring the detent plates into parallelism with the escutcheon plate slots 42, and then the bolts are free to be withdrawn to bring their ends out of the slots 42 so-that thewindow .may be swung. .fter such withdrawal, bolts are again slightly turned to bring the detent plates in front of the brace bars 45 to prevent these bars from leaving the bolts. The sash is now free to be swung inwardly and this is done, and the brace bars 45 are shifted forwardly at their upper ends to bring their studs 44 into the topmost of the notches 43, and the sash will then be held slightly inclined inwardly to permit ventilation but to prevent the entrance of rain or snow. The sash may be lowered any distance and the studs engaged in the corresponding notches.

In Figs. l and 2 the sash is shown entirely down in practically horizontal position, the studs 44 being in the lowermost notches of the escutcheon plate. The outside of the lower sash window pane can now be conveniently washed from ythe inside of the room.

After lowering of the lower sash to hert zontal position, the upper sash may likewise be swung inwardly by first lowering the sash until its pins 24- rcach the lower end of the channel 23, and then withdrawing the ujper bolts 3,1, and then swinging the sash downwardly against the lower sash. It will be noted that the lower ends 23 of the channel 23 are inclined forward slightly. This is for the purpose of permitting rotation of the upper sash without causing binding of its corner (L against the weather board 20. After washing of the outer side of the upper sash window pane this sash is swung back into vertical position and its bolts 3l restored to the channels 23 and the sash is then raised to its upper position.

Preparatory to raising thelower sash to its vertical position the studs44 could be shifted by hand out of the respective notches but preferably means are provided forautoinatically accomplishing. such separation. Such means is clearly shown `in Figs. 2 and 3. Notches 54 are ,provided in the supporting braces 4-5 above their slots 46 and near the lower ends thereof: After, the lower sash has beenraised ashort distancethe supporting braces will drop to receivev the bolts 17 in the notches51l, andthenas the sash is further raisedthe supporting braceswill be automatically shiftedlongitudinally to carry their studs 44: outofthe escutcheon plate notches and the bars will then auto.- inatically be raisedinto parallelism and coincident with the escutcheon plate.

Just beforethe sash is brought into its iinal vertical position,` the bolts 47 aregiveii a slight turn and inward movement in order tov perin-it thebolt ends and thedetent plates 52 to enter the escutcheon plate notches whereafter the bolts are slightly turned tobring the detentplate ends behind the escutcheon plate walls. In orderyto automatically lock the supporting brace bars in their upper position after return of the lower sash to vertical position, friction means are provided. `Such means is clearlyr shown in Figs. 9 and 10. Behindfthe slot Lt2 of each escutcheon plate and at the upper ends thereof the inclined wall section 55 is provided along which the inner end of the respective brace bar stud 4:4; rides as the brace bar reaches its upper position. Each stud has a head 56 at its inner end and the sides of the slot adjacentthe inclined wall section 55 are drawn in as indicated at 57 so that escape of the studs is prevented when the bars are in their upper position, the frictional engagement of the'stud heads with the inclined walls 55 servingto hold the bars in their upper position. Itis possible to swing the lower sash to the first ventilating position without withdrawing stud 56 from the position shown in lFig. 9, be-

cause brace bar i-5 is long enough to permit.

this. If desired the width of the slot 4:2 throughout the length of the supporting bars may be sufficiently contracted to prevent escape of t-lie studs during the entire travel of the supporting bars.

In Fig. a means kare clearly shown for enabling the sashes to be readily swung forwardly without interference and to permit operation of the detent plate 52 as heretofore described. It will vbe noted that-the inner wall sections 17 are slightly inclined,

transversely with reference to vthebracebars so as to afford sufiicient clearance spaces 58 for manipulation of the detent plates 52 to release thelower sashk for swing. The inclined arrangement also permits the insertion offweather strips such as felt 59 along the inner sides of the, pulley stile 19 to be engaged by the `upper sash and to engage along their front edges with the lower sash as clearly shown.

I also provide other efficient weather proof arrangement. Extending from the sides of the uppersash are weather tongues 60 which engage in weather strip pockets 61 securedin the weather board 20. Likewise weather tongues 62 'extend from the sides .of the lower sash andinto lweather pockets 63 secured in the stiles 19. Not only are the pulley stiles inclinedV but ther stiles for the lower sash are fartheirapart than those for the `upper sash, thisaffording-space for the weather strip connection between the front sash and the stile 19 and also giving additional clearance space for the forward swing of the upper sash. Not only does this iinproved construction permit the sash to be readily swung, but it also permits bodily removal of the sashes from the frame to be easily accomplished without need of taking olf guide strips or other part-s. If the lower sash is to be bodily removed, it is shiftedupwards acdistance and then swung forwardly and the bolts Li7 rotated to release the detent plates 52 from the supporting brace bars, and then by tilting the sash transversely one of the trunnion pins will be releasedy whereupon the sash can then be shifted laterally to release the other trun! nion pin. To bodily remove the upper sash, its bolts 31 are withdrawn and the sash swung into horizontal position and then tilted transversely to release the chain engagingtrunnion pins from the frame channel. The trunnion pins being loosely insert-L ed in theirpoclrets 25, these pins can readily be withdrawn andthe sashes then. entirely freed for bodily removal from the window` frame.

In order to permit access to the weight chamber 30 and the weights therein, open ings 65 areprovided in thcinner casings 6G which form the frontwalls ofthe weight chambers, and covers `or closure boards 67 are provided. for these openings. Each board has a detent tongue 68 at its lower endL for engaging in a slot 69 formed in thev inner sill 12, and a screw 69 fastened to the upper end of the board engages in a cross-bar 7 O- whichqengages behind the casing 66 adjacent the .opening therethrough` Upon loosening of the screws the bars 7() will rotate into parallelism with the open-.

ings and the closure board `can be readilywithdrawn to eXposethe openings 65. The weights and the weight chains are thus reads ily accessible.

In Fig. 8 l have shown a connecting end for a corr, when cord is used instead of chains5 for supporting' the weights. This connecting end is in the form of a sleeve 7l which is clamped to the cord end and which at its lower end. pivots a link 72 for receiving the hooks 7 3 on the weights.

To assist in making the window weatherproof, a weather ledge 7 l may he provided at the lower end of the lower sash for snpporting a `weather strip .or cushion 75. 76 and 77 represent lock parts oi usual construction for locking the sashes when in their closed position.

lt is apparent that my improved window is very desirable and useful, not only in residences but in any other building. The use of ladders or the necessity of climbing around outer window ledges is avoided and the windows can be readily washed from the inside of the building. The sashes can be easily and quickly removed bodily from the frames from the inside of the building without requiring the removal of strips or other frame parts as is the case in prior constructions. The swinging feature of the sashes does not interfere with their vertical movements in the ordinary manner. Furthermore3 the lower sash can be adjusted to act as a window ventilator and the expense of special Ventilatingmechanism is avoided.

My improved construction also permits the adequate application of weather strip mechanism without interfering with the ver tical or swinging movements of the sashes. Changes and modifications both in construetion and arrangement are of course possible and l do not therefore desire to be limited to precisely what I have showni and described.
